Hi there,
Just seen your thread and thought I would answer. I work for the company but believe strongly in what we provide.
Although there is an initial 4 days of training it is actually a 6 week programme in which home study is also required prior to returning for assessment at which time should you need further tuition you can. We provide support through email, telephone and even use channels like Facebook to continue the educational process. Our educators who are all experienced nail technicians as well as fully qualified teachers also write blogs and articles to help students through. Obviously all students are also provided with detailed course manuals.
It's simply not fair to say you can't learn in 5 days, of course you can't but in this space of time, and for a really affordable price, you can be shown how to apply each system and with practise become a very good, professional nail technician, everything in life takes time.
I hope this helps.
